RAILWAY-TIE.

Patented July 23, 1907.

Application filed hiarch 2, 1907- Serial No. 360,204,

To all whom it may concern:

Be it known that I SAMUEL M. COLEMAN, a citizen of the United States, residing at .lohnstown, in the county of Cambria and State of Pennsylvania,-have invented certain new and useful Improvements in Railway-Ties, of which the following is a speci cation, reference being had therein to the accompanying drawing.

My invention relates to improvements in railway cross ties and to means for securing track rails thereon.

The object of the invention is to provide a railway cross tie composed of plastic material and metal, which may be produced at a small cost and which will be very strong and durable in use.

The above and other objects are accomplished by the improved construction illustrated in the accompanying drawings, in whiph Figure 1 is a perspective of one end of my improved tie showing a track rail secured thereon; Fig. 2 is a top plan view of the same ;'Fig. 3 is a vertical longitudinal section; and Fig. 4 is an end elevation.

The improved railway cross tie comprises a substan- .tially rectangular body 1 molded of concrete or other suitable plastic material and having secured upon its top a metal plate 2 which forms a chair or seat upon which the track rails 3 may be secured. The metal plate 2 is preferably constructed of a channel beam havihg a rectangular body portion 4 from the longitudinal edges of which depend right angular flanges 5. The

top or upper surface of the plastic body 1 is molded to conform to the bottom or inner surface of the channel beam or plate 2 and these parts are securely fastened toge er by a series of verticalrbolts 6 passed through them. There are preferably four bolts in each series,

that is at each endoi the tie, and the inner ones 7 of each seriesnot only pass through alining openings in the body 1 and plate 2 but also through openings in track rail securing plates or clips 8 which latter are thereby effectivel'y retained upon the top of the tie. The clips 8 are in the form of metal blocks or plates which have their inner enfllsor edges 9 shaped to fit the base flanges oi the track mile 3 and thus effectively hold the same uponthe I top of the lie. Each of the bolts 6, 7 has at its lower end a head 10 between which and the bottom of the body 1 is arranged a washer 11. Upon the projecting upper screw threaded ends of said bolts are nuts 12 beneath which are pre\f erably provided washers 13.

I From the foregoing taken in connection with the drawings, it will be seen that the provision of the chan- 1 nel beam or bar 2 upon the top of the plastic body 1 of l the tie not only serves to greatly strengthen and reinforce said body so as to reduce the danger of its breaking or cracking, but also serves as a strong and durable chair upon which the track rails are firmly supported and secured by the same bolts which unite the plastic body and the channel beam. Furthermore, the (letect the upper edges of the plastic body and the upper portions of its side faces, so that when it is in position upon the road bed there will be little or no danger of the plastic body being injured.

The simplicity of the constructionof thetie permits it to be produced at a comparatively small cost and also renders it exceedingly strong and durable.

While this tie is especially adapted for use on street railways and trolley lines, its use is not limited thereto, as will be obvious,- but it may be used on steam railways and the like, where cross ties are employed upon which to lay the rails.

Having thus described my invention what I claim and desire to secure by Letters Patent is: V I

A railway cross lie comprising a substantially rectangular body of plastic material, a channel metal beam arranged upon the top of sold body and forming an integral covering for the entire top of the some, said beam having along its longitudinal edges depending side flanges of less width than the thickness of the plastic body and embedded in the opposite vertical sides of said body, said body and beam being formed with alined vertical apertures extending entirely through the same, rall clamping plates arranged upon" the top of sold beam and formed with verpresence of two witnesses.
